HTTP POST를 사용하여 이미지 및 텍스트 업로드
읽어 주셔서 감사합니다.
iOS를 처음 사용 multi-part form encoding
하고 iOS에서 사용하여 이미지와 텍스트를 업로드하려고합니다 .
curl
해당하는이 같은 것입니다 :curl -F "param1=value1" -F "param2=@testimage.jpg" "http://some.ip.address:5000/upload"
curl
위 의 명령은 예상되는 올바른 응답을 반환합니다.JSON.
문제점 : HTTP 400 요청이 계속 수신됩니다. 이는 HTTP POST 본문을 작성하는 동안 뭔가 잘못되었음을 의미합니다.
내가 한 일 : 참고로 Flickr API iOS 앱 "POST 크기가 너무 큽니다!" 및 목표 C : 어떻게 HTTP POST를 사용하여 이미지와 텍스트를 업로드? . 하지만 계속 HTTP 400을받습니다.
나는 시도 ASIHttpRequest
했지만 거기에 다른 문제가있었습니다 (콜백이 호출되지 않았습니다). 그러나 개발자가 라이브러리 지원을 중단했다고 들었으므로 더 이상 조사하지 않았습니다. http://allseeing-i.com/[request_release] ;
누군가 나를 도울 수 있습니까?
다음은 웹 서버에 이미지를 게시하는 내 앱의 코드입니다.

XJones 의 대답은 매력적이었습니다.
그러나 그는 언급 / 선언 된 변수하지 않았다 _params
, BoundaryConstant
그리고 requestURL
. 그래서 나는 그 부분을 그의 게시물에 추가 기능으로 게시하여 나중에 다른 사람들에게 도움이 될 수 있다고 생각했습니다.

여기 @xjones가 제공 한 코드에서 번역 된 작동하는 신속한 코드가 있습니다. 도와 주셔서 감사합니다. 당신의 것이 나를 위해 일한 유일한 방법이었습니다. 이 방법을 사용하여 asp.net에서 만든 웹 서비스에 1 개의 이미지와 다른 매개 변수를 전송했습니다.

다음은 Swift 버전입니다. 양식 데이터를 보내지 않으려면 빈 양식 경계를 보내는 것이 여전히 중요합니다. 특히 Flask는 양식 데이터와 파일 데이터를 예상 request.files
하며 첫 번째 경계 없이는 채워 지지 않습니다 .
let composedData = NSMutableData()
// Set content type header
let BoundaryConstant = "--------------------------3d74a90a3bfb8696"

request.setValue(contentType, forHTTPHeaderField: "Content-Type")
// Empty form boundary
composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
// Build multipart form to send image
composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
composedData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

Swift 2.2 에서 NSURLConnection 클래스를 사용하여 양식 데이터가있는 이미지 업로드 :
func uploadImage(){
let imageData = UIImagePNGRepresentation(UIImage(named: "dexter.jpg")!)
if imageData != nil{
let str = "https://staging.mywebsite.com/V2.9/uploadfile"
let request = NSMutableURLRequest(URL: NSURL(string:str)!)
request.HTTPMethod = "POST"
let boundary = NSString(format: "---------------------------14737809831466499882746641449")
let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")
let body = NSMutableData()
// append image data to body
body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(NSString(format:"Content-Disposition: form-data; name=\"file\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(imageData!)
body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
request.HTTPBody = body
do {
let returnData = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
let returnString = NSString(data: returnData, encoding: NSUTF8StringEncoding)
print("returnString = \(returnString!)")
}
catch let error as NSError {
print(error.description)
}
}
}
참고 : 주 스레드 차단을 방지하려면 데이터 업로드 / 다운로드 sendAsynchronousRequest
대신 항상 메서드를 사용 하십시오sendSynchronousRequest
. 여기서는 테스트 목적으로 만 sendSynchronousRequest를 사용했습니다.
나는 당신에게 업로드의 예를 보여줄 수있는 이 .txt 로 서버에 파일을 NSMutableURLRequest
하고 NSURLSessionUploadTask
(A)의 도움으로 의 PHP 스크립트를.
-(void)uploadFileToServer : (NSString *) filePath
{
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://YourURL.com/YourphpScript.php"]];
[request setHTTPMethod:@"POST"];
[request addValue:@"File Name" forHTTPHeaderField:@"FileName"];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultConfigObject];
NSURLSessionUploadTask* uploadTask = [defaultSession uploadTaskWithRequest:request fromFile:[NSURL URLWithString:filePath] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
if (error || [httpResponse statusCode]!=202)
{
//Error
}
else
{
//Success
}
[defaultSession invalidateAndCancel];
}];
[uploadTask resume];
}
PHP 스크립트
<?php
$request_body = @file_get_contents('php://input');
foreach (getallheaders() as $name => $value)
{
if ($FileName=="FileName")
{
$header=$value;
break;
}
}
$uploadedDir = "directory/";
@mkdir($uploadedDir);
file_put_contents($uploadedDir."/".$FileName.".txt",
$request_body.PHP_EOL, FILE_APPEND);
header('X-PHP-Response-Code: 202', true, 202);
